To all whom. it may concern: i

Be it known that I, DANIEL H. A'rwoon, a citizen of the United States, residing in Hendricks township, in the county of Shelby .and State of Indiana, have invented a new and useful lConve er-Protector for Harvesters,.of which the ollowing is a specification,

l reference being had to the accompanying drawing and to the letters and figures of This invention relates to harvesting machines, especially to the type known as self binders in which the cut grain stalks are conveyed to one side of the machine on an endless canvas conveyer mounted above a floor, the grain stalks being elevated on an inclined elevator to the binder, the present invention having reference more particularly to a guard for preventing the entrance of cornstalks or trash onto the {ioor at the foot of the elevator and interfering with the operation of the canvas conveyer, and also preventing injury to the elevating apparatus by corn4 stalks or the like, when harvestin wheat or other small grain grown in fiel s in which corn has been grown the preceding season.

It has been found desirable in some cases to-plant small grain crops in fields which have previously grown corn, and while harvesting machines as heretofore constructed have operated satisfactorilyon clean ground, much trouble has been experienced in their use when harvesting wheat or similar grain on ground that is more or less encumbered by corn stalks which may have been'left on the eld, o'r scattered thereon as portions of manure, the long stalks or portions of stalks particularly being troublesome, especially when they are crooked and disturbed by the driving wheel of the machine or the draft horses passing over the stalks and causin the ends of the stalks to project upwar to be caught between the canvas conveyer and the floor, resulting in choking of the conveyer and necessitating stoppage of the machine to clear away the obstruction,

sometimes requiring the removal of the belt conveyer with consequent loss of time.

.l 50 The object.. ofthe present invention is to provide a protector for guarding against trouble of the above-mentioned character and injury to the canvas belts, a specic object being to provide a guard that shall be so constructed that it may be readily con.

nected to a harvester when its use is found desirable and which may be disconnected so as to remove unnecessary weight when not needed while cutting grain on relatively clean round.

Wit the above-mentioned and minor objects in view, the invention consists in a novel guard for harvesting machines, and in a novel application of the guard to self binders, and in the parts and combinations @5 and arrangements of parts as hereinafter particularly described and pointed out in the a pended claims.

Re erring to the drawings, Figure l is a top plan of'a harvesting machine partially 7@ broken away and having the improvement applied thereto; Fig. 2, a transverse section on the line` A A in Figfl; Fig. 3, a erspective view of a portion of the mac ine showing relative arrangement of the improved protector in connection therewith; Fig. 4, a fragmentary inverted plan of the machine floor and guard connected therewith; Fig. 5, a fragmentary rear elevation of the machine; Fi J6, a sectional elevation of the protector ta en on the line B B in Fig. 2; Fig. 7, a perspective view of the improved protector partially broken away; Fig. 8, a fragmentary sectional view showing slight modications as' on the line A A g5 Fig. 1; and Fig. 9, a fragmentary section also on the line A A Fig. l.

Similar reference characters in the different figures of the drawings indicate like elements or features of construction herein an referred to. i

In order to clearly describe the invention and explain the peculiar function thereof,

a reaper or harvester of well known construction is illustrated and the invention as shown in connection therewith, the machine-i1` Y frame comprising a front bar 1 provided with a draft iron 2 whereby to connect the tongue to the frame, the bar having a downwardly extending oblique angled portion 3 100 which is secured t'o a relatively lower frame bar 4, there being a4 companion rear frame bar 5 having an oblique angled portion 6 which is secured to a relatively lower frame bar 7, an end member 8 being connected to 105 the ends of the bars 4 and `7. The bars l and 5 and other suitable frame members carry the principal gearing, being the main portion of the frame and mounted on a main drive wheel or bull wheel 9, the end 11o member 8 being mounted' on a wheel 10.

The knife bar 11 is mounted on the frame bar 4 and operated by a pitman 12 connected to a crank-wheel 13 which is carried by ashaft 14, other parts of the mechanism being well known. A floor 15 is carried by thevframe bars 4 and 7 and preferably has stiening bars 16 and .17 `secured to the under side ofthe end port-ions thereof. Two bars 18 and 19 are secured to the bars 4 and 7 respectively, and rotatably support a driving roller 20l `adjacently to the oblique angled portions'3 and 6 of the frame bars. Two other'frbars 21 and 22 are secured also to the bars' 4`and 7 respectively, and rotatably support a roller 23, there being a canvas vconveyer belt 24 mounted on the two rollers for receiving the grain after having been cut and conveying 1t to the elevator.

' The floor 15, it will be understood, protects the canvas from injury by the stubble passed over by the conveyer. It will be understood that the floor extends only under the canvas, one end of the floor terminating below the roller'20, so that corn stalks extending upward from the ground may be forced between the canvas belt and the end of the floor, especially when drawn in by the slats with which the belt is customarily provided.

The elevator for receiving the grain from the conveyer may be variousl constructed and in the machine illustrated7 comprises a roller 25 rotatably supported by the oblique angled portions 3 and 6 of the frame bars, a roller 26 suitably supported in a plane approximately above the main wheel 9, a belt 27 mounted on the rollers 25 and 26, the belt extending at an inclined angle there being a roller 28 rotatably mounted somewhat abovethev roller 25, another roller 29 being mounted above the roller 26, the rollers'28 and 29 supporting a conveyer belt 30 opposite the belt 27 so that the belts coto the' belt 27, the latter belt at times being v injured by stalks or posed u portion32 adapted to constitute a continuarlas 'l portion 33 extending operate' to "elevate the grain to the binder 31. The stiff corn stalks at times are ushed up betweenvthle rollers 20 and 27 andp' interfere with thefree `movement of the grain stalks rubbish forced against the under portion thereof, being hitherto un rotected.

he improved protector or guard is comof metal and comprises a horizontal tion of the floor 15 andan oblique angled portion 33 extending upward from the portion 32bei'n composed of sheet metal, the portion 32 w en in normal. osition extend- 'ing from the ioor15v under t e roller 25, the upwardl under the lower portion of the belt 27. joint plate 34 is secured to the upper side of the portion 32 and extends beyond the end thereof and upon the end portion of the floor 15 for supporting the guard and forming a complete closure between the ends of the Hoor the lower side of the portion 33. In Case,

the bar 16 is placed a short distance back from the end of the floor 15 a straight finger 38 extends from the portion 35 of the stiffening bar against the underside of the floor.- Another stifl'ening bar `of similar form to that described is secured to one end portion of the guard and comprises a horizontal portion 35 on and an upwardly extending portion 37 the opposite end of the guard having a somewhatsimilar stiening bar thereon comprising a horizontal portion'35 from which extends a finger 36 and an upwardly extending portion 37, thelatter stiffening bar preferably having a Hange 39 thereon to which a brace 40 is secured, the brace being detachably connected to .the frame ofthe machine, being suitabl connected to the bar 7, which extends un er the bar 5. One end of the horizontal portion 32 of the guard is bent u ward to form a vertical vuard 41 and is ent outward to form a ange 42 adapted to rest upon't-he bar 4 to prevent stalks from being forced onto the normally forward end of the ortion 32 of the guard. The forward enA of the guard is rovided with abrace which comprises a at member 43 secured to the top of the horizontal portion 32 adjacent the angular portion 33, an angular member 44 extending from the member 43 against the upright guard 41, a horizontal member 45 extending from the member 44 upon the fiange 42 and provided with a bolt-hole 46 to receive a securing bolt 47 whereby to secure the guard to the bar 4, an arm 48 preferably being formed on the end of the member 45 and portion 49 adapted to be supported on the having a finger 36 there-4 bar 1 of the frame and having a bolt-hole 50 therein to receive a securing Bolt 51 connected with the bar 1. l The oppesite or rearward end of the ,portion 32 of the guard is bent upward to form an upright and bent outwardly to form a which rests upon the bar 7 for support.

It will be understood that the guard may e variously secured detachably to the frame,

ard 52 ange 53 j l it being adapted to be applied tomany harvesting machines now 1n use as well as to new machines.

In practical use, all corn stalks or sticks that may be thrown up or projected from the ground against the'under side of the guard are stopped or warded off by the under side of the guard and prevented from being forced onto the end of the floor 15, so that the canvas belts of the conveyer and also those of theelevator are completely protected from injury.

Having thus described `the invention, what is claimed as new is l. A conveyer protector comprising a flat plate that has a terminating end on one portion and also an oblique angled eXtension on the opposite portion thereof, the plate having two end portions that are relatively shorter than the terminating end portion and provided each with an upturned guard having an outwardly extending supporting flange, the terminating end portion having a joint plate secured to one side and fin ers secured to the opposite side thereof an extending beyond the terminating end.

2.` A conveyer protector comprising two 'angled plate portions, a secured to the angled portion that has theplate portions at oblique angles each to the other, one of the plate portions having upturned guards on two opposite edge portions thereof, each guard having an outwardly extending supporting flange thereon, the end of one of the plate portions having a joint plate and also fingers thereon projecting from opposite sides of the plate portion beyond the end thereof, stiening bars secured to the outer side of said two supporting brace joint plate thereon, said brace eXtendinCr against one of said upturned guards and also upon the flange thereof, and a brace connected to the remaining one of said plate portions ofthe protector.

In testimony whereof, l aiiix my signature in presence of two witnesses.
